What is ammo and how do I use it?

Ammo is fired from your Battle Carrier's guns when you defend your base. You can upgrade ammo and unlock new ammo types in the Ammo Forge (check out the shop for it). In combat, your Battle Carrier is always floating nearby, ready to rain down some heavy punishment. Simply drag the ammo icon on the area you wish to attack, and watch the hellfire unleashed. Different types of ammunition have different purpose and effects which range from poison DoT to freezing enemy units to dealing massive splash damage, etc.
